The Cutler-Hammer® MVX9000 Series
sensorless vector adjustable frequency
AC Drives from Eaton’s electrical business
are designed to provide adjustable speed
control of 3-phase motors. These
microprocessor-based, sensorless vector
drives have standard features that can be
programmed to tailor the drive’s
performance to suit a wide variety of
application requirements. The MVX9000
sensorless vector series utilizes a 32-bit
microprocessor and insulated gate bipolar
transistor (IGBTs) which provides quiet
motor operation, high motor efficiency and
smooth low speed performance. The size
and simplicity of the MVX9000 Series makes
it ideal for hassle free installation where size
is a primary concern. Models rated at 480V,
3-phase, 50/60 Hz are available in sizes
ranging from 1 to 10 hp. Models rated at
240V, single- or 3-phase, 50/60 Hz are
available in sizes ranging from 0.5 to 7½ hp.
Models rated at 115V, single-phase,
50/60 Hz are available in the ¼ to 1 hp size
range. The standard drive includes a digital display, operating and programming keys on
a removable keypad. The display provides
drive monitoring as well as adjustment and
diagnostic information. The keys are utilized
for digital adjustment and programming of
the drive and for operator control. Separate
terminal blocks for control and power wiring
are provided for customer connections.
Other features provided as standard include
built-in DC braking, RS485 serial
communications and PID control.
